Abstract

See full text

A magnetizing method includes the steps of preparing a rotor comprising a rotor core having a magnet insertion hole and a permanent magnet provided in the magnet insertion hole, placing the rotor so as to face a tooth around which a winding is wound, rotating the rotor in a first rotating direction by a first angle θ1 from a rotational position where a center of the magnet insertion hole in a circumferential direction of the rotor core faces a middle portion between both ends of the winding in the circumferential direction and supplying electric current to the winding, and rotating the rotor in a second rotating direction opposite to the first rotating direction by a second angle θ2 from the rotational position direction and supplying electric current to the winding. The second angle θ2 is smaller than the first angle θ1.
